  1. 8th Grade math chart

  2. Perimeter Perimeter is the outside edge of an object square =4s rectangle = 2l+2w

  3. 20 18 • Find the perimeter of a square the side length is 5? • Find the perimeter of a rectangle if the side length is 5 and the others 4?

  4. Volume Prism V = B times h Cylinder V=B times h pyramid V=1/3 B rimes h cone V=1/3 B times h sphere V =4/3 r3

  5. Volume What’s the volume of the if prism the area of the base is 20 and the height is 3 whats the volume of a cylinder if Big B is 20 and the hieght is 4 • 60 • 80

  6. volume What is the volume of the pyramid s base is 30 and the height is 6 divded by 3 What is the volume of a cone if the area is 10 and the hieght is 5 divided by three • 60 • 16.66

  7. Word problem Sphere if the radius is three times pi divivded by three • 3.14

  8. Big P stands for perimeter of the base

  9. BIG B • stands for Area of the base

  10. area square A=s squared • rectangle A=length times width triangle A=base times hiegth divided by 2 Trapezoid base 1 times base two times height Circle A = times radius squared

  11. circumference times d

  12. Word Problem • 3.14 times 10 equals= 31.4

  13. Pi pi equals 3.14

  14. Pythagorean theorum A squared plus B squared equals C squared

  15. Simple interest formula I = prt

  16. Surface area Square = 6 sides squared Prism lateral =P times h Prism total=P times h plus 2 times B Pyramid lateral=P times l Pyramid total = ½ P times l plus area of the base Cylinder lateral =2 times height Cylinder total=2 times radius times hiegth

  17. Cube S = 6s squared if the face is 7 If the perimeter of the base is 5and the hieght is 6 • 49 • 30

  18. If the perimeter of the base is 8 times 4+16 If the big p is 4 times 6 • 48 • 12

  19. If the perimeter is 6 the length is 5times 8 3.14times 5 times 6 • 19 • 94.2
